naming is way off.

AngularFirestore isn't even an allowed naming anymore.

And the code vs the guide is way off.

If You're Using Angular 13x, Try Using The Following Imports In Your 'app.module.ts'

import { AngularFirestoreModule } from '@angular/fire/compat/firestore'; import { AngularFireModule } from '@angular/fire/compat'; ......... imports: [ AngularFireModule.initializeApp(environment.firebase), AngularFirestoreModule ];

Worked Fine With Me.
